n claims. (c1. l16s- 118) This invention relates to improvements in diesets. Bya die set is meant a pair of die supports composed of a top unitand a bottom unit, to each of which is attached dies, punches, cutters,forming dies or any of the other mechanism conventionally used. Thedies, punches, etc., likewise are used in pairs after they have beenattached to the die set. Frequently the dies are referred to as male andfemale dies, such as in the case of forming dies or punch dies. l Theconventional die set has two or more xed alinement of the dies when inoperation. These iixed guide posts, through use, become worn or out ofline, and this out-of-alinement condition is a drawback, as itnecessitates discarding the die set and gives rise to considerable wasteofl equipment and loss of time.

tion this disadvantage had been recognized and efforts made to providestructures to eliminate the objection. Usually, however, this wasaccomplished by the use of collars through which the guide posts extendinto the lower one of the supporting members of the die set. Hence, suchproposals do not entirely obviate the objection. The primary purpose ofthe present invention is to remove such objection, and this I accomplishby specially constructed guide posts which may be adjusted tore-establish, correct alinemenvt. This will result in a saving of partsand a very substantial saving in money to manufacturers lengaged in theuse of 4die sets. l

With the above object set forth and with other objects in View whichwill appear as the description proceeds, the invention consists in thenovel features hereinafter described `in detail, illustrated in theaccompanying drawing and more particularly pointed out in the appendedclaims.

In the drawing, .t .y Fig. 1 is a perspective view of a die set-providedwith my improvements.

Fig. 2 is a top plan view of the same.

Fig.3 is a side elevation, partly in vertical section.

Referring to the drawing, 4 designates the lower stationary member and 5theupper movable member of a die set, the latter being guided in itsreciprocation by means of guide posts E,

which pass through holes 1 bored in the upper member.

' Heretofore, it has been customary to bore holes Prior to my nven- Yguide posts to provide proper apposition and may be clearly understood,and I am aware that post with an enlarged base 8 that rests on the uppersurface 9 of the member 4. The base is of larger diameter than thefpostand is provided with drilled holes I0 for the accommodation of dowelpins II, and countersunk holes I2 for the reception of socket head capscrews I3. The dowel pins extend into holes I4 drilled in the member 4,and the screws extend into threaded holes I5 tapped in said member. Itmay be seen from Fig. 2 that the holes I4 and I5 are arranged about' theaxes of the guide posts and obviously either post may be removed fromthe member 4 whenever desired or may be shifted aboutits own axis. It isalso apparent that as the post per se does not extend into the member 4,either post can be shifted toward or away from the other,A

posts having enlarged bases abutting one of said faces and detachablysecured to the member havving the last mentioned face, theother memberbeing provided with holes through which the guide posts extend, theportion of the member lto which the posts are secured being imperforatedirectly in alignment with the posts.

2. A die set comprising opposed members havl ing confronting faces,guide posts having enlarged.

bases abutting one of said faces and detachably secured to the memberhaving the last mentioned face, theI other member being provided withholes through which the guide posts exv tend, the endof each guidepost-.adjacent its base f terminating between the faces ofsaid members.

v 3. A die set comprising opposed members'having confronting faces,guide posts having enlarged bases abutting one of said'faces anddetachably secured tothe member having the last mentioned face, theother member being provided with holes through which the guide. postsextend, the portion of the member to which the posts are secured beingimperforate directly in alinement in the lower member 4 for thereception of the with the posts.

4. A die set comprising a lower member having a substantially planeupper surface, guide postshaving enlarged bases with substantially planebottoms resting directly on said surface, means detachably connectingthe bases of the posts to said member, said member being imperforatedirectly in alignment with the posts, and

bases provided with plane bottoms resting'directly on said surface, saidmember being imperforate directly in alignment With the posts,

the base of each guide lpost being aprtured, fas tening means extendingthrough the apertures and detachably securing the bases to saidmember,and an upper member having holes through which the guide posts extendfor guiding th member relatively to the lower member.
